Rockies-focused explorer PureWest Energy LLC said it has secured a deal to supply carbon-neutral natural gas for a fleet that serves Pierce County, WA.

The Denver-based independent is partnering with United Energy Trading LLC (UET) to provide Pierce Transit with the responsibly sourced gas (RSG). The amount of gas to be sold was not provided.

Pierce Transit, whose fleet is 80% fueled with compressed natural gas (CNG), covers 292 square miles, or roughly 70% of the county’s population. UET would physically deliver the supply.

“While operating the majority of its buses on CNG offers environmental benefits over traditional fuels, there is still an environmental impact,” according to the partners. Transitioning the CNG fleet “means 80% of Pierce Transit’s buses will be running on certifiably carbon-neutral RSG.”

The agreement “enables Pierce Transit to balance the needs of our customers with a responsible, lower-carbon energy supply,” said CEO Mike Griffus.

Privately held PureWest, considered one of Wyoming’s top natural gas explorers, controls 115,000 net acres-plus in and around the prolific Pinedale and Jonah fields. Affiliate Ultra Resources Inc. in October expanded the producer’s RSG portfolio with an agreement to reduce direct and indirect (Scope 1 and 2) emissions from two well pads. The wells were certified by Project Canary.

PureWest plans to certify an additional 779 wells on 38 pads by the end of this year.

“This unique partnership further accelerates our commitment to being an industry leader in delivering lower carbon energy solutions,” said PureWest CEO Chris Valdez. 

UET this year became a “carbon footprint offset company,” and 100% of the business operates with renewable energy, said President Thomas Smith. “We want to help our customers manage their emissions as well.”

UET has operations throughout the continental United States and Canada. It purchases, transports and/or sells RSG, renewable natural gas, carbon offset gas, renewable fuels, carbon offsets and renewable energy certificates.
